    100 seconds, the simplifying insight being that, for our purposes, the collision behavior of the ants is equivalent to the ants simply passing each other and swapping name tags.

    The minimum time approaches zero as the minimum ant-to-ant spacing approaches zero (and since this is a math puzzle, we can presumably treat the ants as dimensionless points).
